How to automatically push APK from mobile to wear?

This is my first question on Stack Overflow so please let me know if I should format it differently.

I am writing an Android Mobile (phone) app that will interact with a companion Android Wear (watch) app. Both of these apps work when I install them directly via adb. I am trying to create an APK that will install onto phone from an email attachment and push the companion app to my watch automatically. However, when I create an APK and install it via email attachment, this APK does not successfully push the companion app to my watch.

When I read the installation logs via $ adb -d logcat | grep 1329, I get the following result (below). Would anyone happen to know what I am doing wrong? I have attempted to look up the error messages online but have not found anything useful.

There are also many, many lines of W/StreamManager( 1329): Dropping non-bitmap icon from notification. interspaced through the output. I have removed them for clarity.

Notes

I am using the command-line SDK toolset, and have signed apps in accordanace with the "Package Manually" instructions on the Android developer's webpage and "Signing your Applications".
I am currently using the Android SDK command-line toolkit but am willing to use Android Studio if necessary.
Hardware: I am testing this on a Samsung Galaxy S5 and an Asus ZenWatch 2.
I renamed the wear apk from "wear-release-unsigned.apk" to "wear_release_unsigned.apk" when I put it in the mobile app's /res/raw/ directory. Contrary to the name, it is actually signed.
Original source code is available on github.

Thank you all, very much.

Update

I have bumped the versions on the phone and wear app. Logs follow below. Like last time, these are grep'ed for 1329. I have also removed the "dropping non-bitmap" lines.

Solution

Well, I solved my own problem. According to the Android developer webpage, "It's important that you read and understand Signing Your Applications". They then link to a page I did not fully read.

By adding a proper configuration to my build.gradle file instead of signing manually with jarsigner, everything installed just fine.
